ROAD-DRAG.

Specification of Letters Patent.

Patented'ripr. 21, 1914.

Application filed July 24, 1912. Serial No. 711,297.

17 0 all whom it may con cern Be it known that I, PERRY G. DOWELL, a

citizen of the United States, residing at Joliet, in the county of Willand State of Illinois, have invented certain new and useful Improvementsin Road-Drags, of which the following is a specification.

This invention relates to road drags, and has for one of its objects toprovide a device of the above character which may be cheaply and durablyconstructed.

The drag forming the subject matter of the present invention, comprisesa plurality of corrugated plates or sections which operate upon theground for leveling the latter, and suitable means for connecting orsecuring the sections or plates together.

The invention further provides a scraper bar or member disposed inadvance of the corrugated plates, said bar projecting downwardly belowthe operating surfaces of said corrugated plates.

With the above and other objects in view, reference is to be had to thefollowing description and to the accompanying drawings wherein,

Figure 1 is a top plan view of a drag constructed in accordance with thepresent invention; Fig. 2 is a front elevation thereof; Fig. 3 is a sideelevation of the drag; Fig. 1 is a detailed perspective view of one ofthe plates or sections of which the drag is constructed; Fig. 5 is aview of a drag comprised of curved plates not corrugated; and Fig. 6 isa similar view of a drag in which a single curved plate is employed inlieu of the several plates.

Throughout the following detail description and on the several figuresof the drawings, similar parts are referred to by like referencecharacters.

A, road drag constructed in accordance with the present invention,comprises a plurality of plates or sections secured by spaced angle ironmembers and a scraper bar secured to the sections or plates by shortangle iron members whereby said bar is rigidly fastened to the firstplate, and disposed in advance thereof for leveling the ground, previousto the action of the plates on the latter. Further reinforcement of thestructure is obtained by securing the clevis fastoning plates to thefirst section, and fastening the clevis through the clevis fasteningplate and the scraper bar, as will be hereinafter disclosed.

The plates or sections 1 are of corrugated material, and the centralportions thereof are bent or curved downwardly, as at 2, the edges ofthe plates lying in the same plane, and provided with apertures oropenings 3, whereby he several plates may be secured to the angle ironframe members t in any desirable manner. By having the plates 1corrugated, the operating surfaces 2 wiich operate upon the ground, notonly are adapted to yield, but such corrugations stiffening the plates.

In advance of the first plate 1, is mounted the scraper bar 5, thelatter being preferably rigidly secured to the first plate by the shortangle iron extensions or splice bars 6 bolted or otherwise detachablyfastened to the frame angle irons 4, and said plate 1. This scraper bar5 is preferably constructed from angle iron, the lower or scraping edge5 eX- tending below the plane of the operating surfaces 2 for cutting orscraping the ground into a crude level condition, previous to the finalaction on the ground by the operating surfaces 2.

The draft rigging employed in moving the drag, is fastened to the pairof clevises 7, supported by the scraper bar 5. A clevis fastening ormounting plate 8 1s fastened to the first plate 1, while its forwardterminal is provided with an aperture adapted to register with a secondopening in the scraper bar 5, through which the bolt may pass forfastening the clevis 7 to the drag. From the foregoing, it will beobserved that any pull on the clevises 7, will not tend to strain orpull the scraper bar 5 from the sections at the point of the mounting ofthe clevises, since such action is prevented by the plates 8, which arerigidly fixed on the adjacent plate 1. I

A road drag constructed in accordance with the above description,requires simply a plurality of corrugated plates or sections,

and a plurality of angle iron members of plates or drag members Withoutcorrugations. The plates in Fig. 5 are mounted in a manner similar tothe plates in Fig. 1. In Fig. 6 the several plates 1 of Figs. 1 and 5are replaced by a single plate 1 comprising several curved surfaces tooperate upon the ground said plate being fastened at the upper curvedportions 1 to the angle irons by rivets or other suitable means.

Having thus fully described my inven tion, What is claimed as new is:

In a drag the combination of a scraper bar of angle material having apendent flange and a horizontal flange, splice bars spacedlongitudinally of and connected to the horizontal flange and extendinginwardly therefrom, a plate extending longitudinally of the scraper barin the rear thereof and having a longitudinal edge di rected toward thescraper bar, said plate having a longitudinal depression intermediateits edges and having its edge portions fixed to the splice bars a seriesof similar plates arranged edge to edge at the rear of the first plate,and frame bars fixed to the splice bars and extending transversely ofand being connected to the last named plates.

In testimony whereof I affix my signature in presence of two Witnesses.
